Study on MOBILE01 Website 3C Products \ue2Open Box Experience\ue2 Sharing Phenomenon
No full textThis study uses Business Next magazine 2008 number one rating 3C product discussion group website Mobile01\ue2s \ue2open box experience\ue2 professional writers as study objects. The purpose of this study is to explore \ue2open box experience\ue2 sharing phenomenon and to understand writers\ue2 motivation and feedback in order to analyze the website management implication on this phenomenon.
This study is based on soial cognitive theory, explores each dimension based on social cognitive theory and related items. The structure of this study includes people (capacity, attainment, enjoyment, positive feedback outcome expectation), environment (source of the product, exchange, feedback), behavior (the process of open box experience publication, reactions to feedback).
This study adapts case study method. Researcher explored related journals, observed study object website. Based on the basic question categorization structure to construct interview questions, invited \ue2open box experience\ue2 experts and conducted open-ended expert in-depth interview. After each interview, the interview contents were typed into transcription. The transcription and the website data were used to describe \ue2open box experience\ue2 sharing phenomenon. Then the theme words which are related to the study were extracted from the transcription and became this study\ue2s basic elements. There are 264 themes extracted, coded and categorized in order to focus on the question. Finally, there are 252 effective themes selected and analyzed. Based on the major study findings, there are two conclusions:
1. The motivation of \ue2open box experience\ue2 writing is based on people\ue2s capacity, attainment and enjoyment. It also resulted by positive feedback outcome expectation by \ue2self purchase\ue2 or product source provided by online environment as well as exchange and feedback.
2. Negative feedback can result in keeping \ue2open box experience\ue2 writers from sharing and cause the lost of information for websites.
Based on the above conclusions, this study provides suggestions to website owners, administrators, product vendors, \ue2open box experience\ue2 writers and readers. The suggestions can be used as references for website owners, administrators, product vendors when they are forming management strategies

Abstract
Critical velocity (CV) and critical power (CP) have been proposed to be effective indirect anaerobic threshold methods in monitoring training and predicting performance of rowing respectively. The purpose of this study was to compare these two indexes in predicting indoor rowing performance by combining different physiological variables, including maximal oxygen uptake ( VO2max ), anaerobic threshold (AT4) and modified Wingate test, which are important physiological variables in endurance performance. In addition, whether or not the physiological variables (VO2, VCO2, VE, HR, [La-]) under these two critical intensities were stable was also examined. Fifteen elite female rowers (age 20.73± 1.44 years, height 1.64 ±0.35m, weight 56.64±4.38kg) were recruited in this study. VO2max (2.47 ±0.47L) and AT4(157.81 ±22.08W) were measured during a discontinuous graded exercise test, starting at 100W, on a Concept II ergometer increased by 25 W for each 3-min stage. Four test times of duration 90s, 240s, 600s, and 1200s were used to determine CP (139.49 ±20.37W), whereas CV( 4.00 ±0.14m/s) was estimated by 400m, 600m, 800m, 1000m maximal exertion trials in different days as well by using Linear distance-time model. Peak power (353.48 ±27.71W), maximum power (350.12 ±26.72W), minimum power (336.85 ±21.58W), mean power (314.44 ±27.87W), fatigue index (max power - min power/ mean power) were obtained using a modified Wingate test protocol (30s sprint) on the ergometer. Physiological variation of intensity at CV and CP, including VO2, VCO2, VE, HR, [La-], were measured every 5 minutes in 20-min constant rowing tests. The results of study showed that VO2max, AT4, CP, CV, peak power, mean power were significantly correlated with 2000 indoor rowing performance (r=?0.84, ?0.85, ?0.81, ?0.97, ?0.66, ?0.67, P<0.01). By submitting mean power, fatigue index, VO2max, AT4 with each index to a stepwise regression analysis, it produced two individual critical concept models as following to predict 2000 indoor rowing performance: CV model: T2000= ?131.83 CV(m/s)?1.00 fatugue index(%) +1023.91 (R2=0.96, SEE=4.10, p<.05); CP model: T2000=?22.59 VO2max(L/min)?.38AT4(W)+608.58 (R2 =0.82, SEE=8.05, p<.05). When rowing at CV on indoor ergometer (14±4 min), VO2, VE, HR, [La-] didn’t reach steady state and VCO2 was not different at different time points. Under CP, VO2, VCO2 didn’t change with time, however, there were significant difference of VE, HR, [La-] at different time points. Our findings in this study indicated that CV has more predictive power, representing as anaerobic threshold, than AT4 to predict rowing performance. Besides CV, fatigue index from modified Wingate test is also an important determinant for 2000-m performance of female rowers. Therefore, comparing with CP, CV could be used when applying critical concept in training and evaluate indoor performance in rowing. In addition, both two-parameter-derived CV and CP in rowing do not represent sustainable steady state intensities.
Key words: critical velocity, critical power, anaerobic power, energy expenditure, rowing, performance.

Abstract
The purpose of the study was to compare four tests of static balance with force platform test (two-leg stance test). Fifty male university students (average age = 21.26±2.42 years old) were recruited in this study with balance-order testing sequence. Repeated-measurement and one-way ANOVA were used to identify the differences among tests. Subjects participated in five tests, including force platform test (two-leg stance test), one-leg stance test (eyes-closed), Bass stick test-lengthwise, Bass stick test-crosswise and Stork stand test. The results of Pearson’s moment product correlation are as follows:
(1) One-leg stance test was highly correlated with two-leg stance test (r = 0.864, 0.757), no matter being evaluated with time-counting or in force platform.
(2) Stork stand test also was highly correlated with two-legs stance
Test (r = 0.775, 0.644). Therefore Stork stand test also can
measure individual static balance ability.
(3) Bass stick test-lengthwise and Bass stick test-crosswise were less
correlated with two-legs stance test（r = 0.269, -0.345, 0.356, -0.432）.
Therefore Bass stick test-lengthwise and Bass stick test-crosswise
were not as suitable as other two tests in measuring individual static
balance ability.
These results indicated that one-leg stance test (eyes-closed) is the most valid test in measuring individual static balance.
Key words: static balance ability, static balance test
A Study of Zolt\uc3\ua1n Kod\uc3\ua1ly's Sonata for Unaccompanied Violoncello, Op.8
No full textThe twentieth century was a period of non-stop innovation for western music. During that time Hungary also broke free of communism. It was because of under these circumstances which helped Kodaly developed his own style. Sonata for Unaccompanied Cello, Op. 8 in 1915 is one of Zolt\uc3\ua1n Kod\uc3\ua1ly\ue2s (1882-1967) earlier works. It contains influences of polyphonic style music from Giovanni Pierluigi da Palestrina and Johann Sebastian Bach as well as the inflections and nuances of Debussy and Hungarian folk music.
The article will focus on different perspectives of Kod\uc3\ua1ly\ue2s Sonata for Unaccompanied Cello, Op.8. It first gives a brief summary of Kodaly\ue2s historical background. Then it discusses the details and differences in tonality and modulation that has been used in this piece. Finally, the article will discuss performance technique focusing on both hands and preparation practices.
The writer wants to assist the reader whoever plays this piece in the future can easy to overcome any predicament in the music. Aside from technical aspects that Kodaly used, the author hopes the reader will understand the connotation and messages Kod\uc3\ua1ly tried to embody in Sonata for Unaccompanied Cello, Op. 8
